phagocyte

 [fag´o-sīt]
any cell capable of ingesting particulate matter, usually referring to a microphage, macrophage, or monocyte. They ingest microorganisms and other particulate antigens that are coated with antibody or complement (opsonized), a process mediated by specific cell-surface receptors. Other cell types exhibit phagocytosis, but not specific phagocytosis of opsonized particles.

phag·o·cyte

(fag'ō-sīt),
A cell that can ingest bacteria, foreign particles, and other cells. Phagocytes ingest and kill microbes, present antigen to lymphocytes, scavenge degenerating material, and release mediators. classes: 1) microphages, polymorphonuclear leukocytes that ingest chiefly bacteria; 2) macrophages, mononucleated cells (histiocytes and monocytes) that are largely scavengers, ingesting dead tissue and degenerated cells.

phagocyte

(făg′ə-sīt′)
n.
A cell, such as a white blood cell, that engulfs and absorbs waste material, harmful microorganisms, or other foreign bodies in the bloodstream and tissues.

phagocyte

[fag′əsīt]
Etymology: Gk, phagein + kytos, cell
a cell that is able to surround, engulf, and digest microorganisms and cellular debris. Fixed noncirculating phagocytes include the fixed macrophages. Free circulating phagocytes include the polymorphonuclear neutrophils . phagocytic, adj.

phagocyte

A cell (e.g., macrophage, neutrophil, eosinophil, etc.) capable of phagocytosing (engulfing) particles (e.g., bacteria and other microorganisms, foreign matter, etc.).

phag·o·cyte

(fag'ō-sīt)
A cell possessing the property of ingesting bacteria, foreign particles, and other cells. Phagocytes are divided into two general classes: 1) microphages, polymorphonuclear leukocytes that ingest chiefly bacteria; and 2) macrophages, mononucleated cells (histiocytes and monocytes) that are largely scavengers, ingesting dead tissue and degenerated cells.
[phago- + G. kytos, cell]

phagocyte

An AMOEBOID cell of the immune system that responds to contact with a foreign object, such as a bacterium, by surrounding, engulfing and digesting it. Phagocytes occur widely throughout the body wherever they are likely to be required. Some wander freely throughout the tissues. They include macrophages and neutrophil polymorphonuclear leukocytes (‘polymorphs’). From the Greek phago , eating and kutos , a hollow or receptacle.

phagocyte

a cell that is capable of amoeboid movement, flowing round and engulfing material from its surroundings. Such cells are capable of discriminating between different particles. For example, phagocytic white blood cells will engulf only certain BACTERIA. Phagocytes form an important defence mechanism in higher animals, particularly against bacteria which are engulfed and digested. See MACROPHAGE.
